PrintGuard 2.0 — ShuffleNetV2 + few-shot prototypical network, TFLite via LiteRT, ≈5 MB, runs unmodified in the browser (Pyodide) and on CPython [P]

Hi everyone, I shared PrintGuard here about a year ago as a few-shot FDM failure detector built on a ShuffleNetV2 backbone classified by a prototypical network — the model from my dissertation, packaged with a hub and a web UI. v2.0 ships today and is a complete rewrite of everything around the model, so I wanted to walk you through what's changed and what hasn't. What hasn't changed is the model. It's still a ShuffleNetV2 encoder classified by nearest prototype, trained for few-shot FDM fault detection in
